The FS45 – innovative engineering with an optimized structure for long-life and high strength to weight ratio. The shear is designed with a significantly enlarged pivot group that eliminates the need for auto guide and dramatically improves performance and durability of the shear. There is nitrocarburized swivel components for durability, and the upper and lower jaws are made from 6″ high-yield structural plate steel, which eliminates the need for laminations.
